T 0 all whom it may concern Be it known that E, Emerson E. Pincus 'rinn. residing at flackensack, in the county of and State. of New Jersey, have invented certain new and useful Improvements in Delivery ldechanism for Envelopeiilaking Machines, of which the followlng is a specification.

This invention relates to delivery mechanism for envelope-making machines.

An object of the invention is to provide a delivery mechanism which is positive and e'iiicient in its operation and which is at the same time of simple and practical construction.

A further object is to provide a delivery mechanism in which free and unobstructed access is given to all the envelopes in the delivery chute at all times.

A further object is to construct the device so that certain elements thereof are connected together and assembled with the delivery table so that they may be handled as an entity when placing them into and out of functioning position within the machine.

A more specific object is to provide a pusher for moving the finished envelopes into an appropriate delivery chute and to provide retaining means for holding the envelopes within the delivery chute which is positively operated by the IHOVQIDGJES of the pusher.

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elen'ients, combinations, arrangements of parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawings which are to be taken as a part of this specification, and in which I have shown merely a preferred form of embodiment of the invention Figure l is a vertical. sectional view through a portion of an envelope-making machine including a delivery mechanism constructed and operated in accordance with this invention. 7 I

Figure 2 is a diagrammatic illustration for graphically showing the dili'erent positions of moving parts present in Fig. 1'.

Figure 3 is a top plan view of the structure seen in Fig. 1.

Figure e is an enlarged plan view of a portion of the mechanism seen in Fig. 3, and

Figure 5 is a vertical sectional view taken substantially upon the plane of line V of Fig. 1, and looking in the direction of the arrow. v

Referring to the drawings for describing in detail the structure which is illustrated therein, is the reference character L indicates a horizontal delivery table at the opposite sides of which rise vertical wall members 1 and 2 so as to constitute a delivery chute or giiiide-way along which the finished envelopes are fed from the drying chain, (not illustrated) as will be readily understood by those familiar with this class of machines. The envelope is picked out of the drying chain by a picker device, as 3, and is swung around by the picker device into position in front of and upon a pusher plate 4;, as indicated by the arrows in Figs. 1 and E2. The pusher plate then moves forward and carries the envelope into position within the chute formed by the table la and the walls 1 and 2, as clearly seen in Figs. 1 and 2. ""he push er plate then moves backwardly and receives another envelope which it at once delivers into the chute, the operation being repeated continuously throughout the running of the machine, and theenvelopes being stacked one against the other within the chute. each new envelope acting to push forward the stack along the chute. A holder block is preferably present within the chute.

This block is mounted to slide readily along the table and its purpose is merely to hold the envelopes against falling forward. it moves forward readily as envelopes are added to the stack by the pusher plate.

To retain the newly adc ed envelopes from falling back as the pusherv plate recedes, upper and lowerstops, G and H respectively, are provided. The upper stops G are duplicated at opposite sides of the chute and each consists of-a gravity latch member 6 pivotallyhung upon a pivot wire7 carried by a guide plate 8. The plate 8 is arranged horizontally spaced substantially parallel above the upper surface of the table L. It is supported by a bracket member 9 carried by the wall member 1, or 2. The bracket member is of inverted L-shape. Its shorter leg 10 extends horizontally above the guide plate and its longer leg 11 depends into adjustable engagement with a carrying member 12 supported upon the outer surface of the wall member 1, or 2. The leg 11 is slotted longitudinally, as at 13, to receive a clamp bolt 1 1 projecting from the carrying member 12, and

the carrying member is preferably formed plates 18. Suitable screws, as 19, or other means, may be employed for retaining the walls 1 in any position of lateral adjustment relative to the plates 18. Since the bracket members 9 are carried solely upon the Wall members 1 and 2 it is apparent that they will move toward or away from each other whenever the wall members are moved. In this way the stops G 'are always maintained in proper position for cooperating with envelopes of the respective sizes for which the walls 1 and 2 are adjusted to cooperate. At the same time a wide open space 20 is afford ed between the two stops G where nothing overlies the upper edge of the stacked envelopes. This is important in that it aitords free and unobstructed access to all of the envelopes in the stack at any time. It also avoids necessity for independent adjustment of the stopsG whenever the side walls 1 and.

'2 are adjusted.

. The lower stop H consists of a plate 21 carried by a bracket 22 which is pivotally 'mounted, as at 23, between suitable legs 2 1 fixed to or formed integral with the table at the under surface thereof. This plate is provided with a plurality of fingers 25 which normally project upwardly through registering openings 26 formed through the table so that the upper ends of these fingers are adapted to constitute directly the lower stops for the envelopes. A tension spring 27 is arranged for urging the bracket 22 upwardly to hold the fingers in stopping position.

The pusher plate 4 is carried by an arm 28 which is pivotally mounted upon a shaft 29 and which has an extending portion 30 connected by a link 31 with a rocker member 32 carrying a roller 33 in the path of a cam 34. The cam 34 is mounted upon a shaft 35, and the movements of the cam, supplemented by the action of a tension spring 36 connected with the extension 30, causes swinging movement of the pusher plate between its two positions; that is, between its rearward or receiving position, and its forwarder delivering position. The extension 30 may, if desired, be provided with a slot 37 longitudinally therein to be engaged by the pivot bolt 38 of the link 31 so that the point of connection of the link with the extension 30 may be adjusted at will for altering the precise extremes to which the pusher plate is moved by the cam.

Projecting from the side of the arm 28 is a pin 39 arranged for engaging a cam plate 40 which is carried by the braeket22. The cam plate 40 is pivotally mounted upon the bracket 22, as at 41, and is held against swinging in a downward direction by means of a stop portion 12 formed upon the bracket. The relation of the pin 39 and the cam plate is such that as the arm 28 moves forward to delivering position the pin will engage the upper surface of the cam plate and ride therealong causing the cam plate and consequently the bracket 22 carrying the stops H, to swing downwardly until the pin rides oil of the upper end, as 43, of the cam plate and allows the spring 27 to return the parts to their normal position.

As seen by a study of Fig. 2, the parts are so arranged that the stops H are held in a position belowthe upper surface of the table L at a time while the envelope, as 44, is pass- .ing over said stops.

As the arm 28 returns to its receiving position, the pin 39 engages the under surface of the cam plate and swingsthe cam plate upwardly, as seen in Fig. 1. When the pin has passed the cam platefalls again to its position against the stop 42 ready for a subse quent movement of the pin along the upper surface of the cam plate.

The lower edge of the pusher plate is, 0 course, suitably formed, as at 45, for allowing the pusher plate to return after the stops H have moved upwardly to stopping position behind the delivered envelope. 2

The table L is detachably connected with the main frame work 46 of the machine by means of suitable screws, or the like, as

17, the removal of which will permit the table to be lifted entirely away-from. the machine. The heads 0t the screws 17 are directly in the face of the table 'so that they may be ver easily taken out whenever occasion arises for the making of repairs or adjustments" to the mechanism above described. This is of considerable importance in view oi the fact thatfithe supporting plates 18, and with them the side wall members and the upper stops, as

well as the lower stops and their carrying bracket, are all mounted directly upon the table so that they are all bodily removable as a single entity with the table.

The supporting plates 18 may be connected with the table L in any manner, but

construction without departing from the scope of the invention as defined in the following claims, it is intended that all mat ter contained in the above description, or shown in the accompanying drawings, shall be interpreted as illustrative only and not in a limiting sense.

The table L may be formed with an abutment port-ion 49 arranged asa stop to be 'making machines, the combination with a engaged by the upper portion of the bracket 22 for limiting the upward movement of said bracket.

The side wall members 1 and 2 mayhave portions cut therefrom to provide openings 50 for facilitating unobstructed movement of said side walls without interfering with the operation of the stops 8.
